The Amazing Quiz On Computer Peripherals

Explanation
A peripheral device is a device that is connected to a computer but is not an integral part of it. It is used to input or output data from the computer. A printer, mouse, and scanner are all examples of peripheral devices as they are connected to the computer to perform specific functions. However, the CPU (Central Processing Unit) is the main component of a computer that performs calculations, executes instructions, and manages the overall operation of the computer. It is not considered a peripheral device as it is an essential part of the computer itself.

Explanation
A USB hub is a device that allows for the expansion in the number of available USB ports. It is used to connect multiple USB devices to a single USB port on a computer or other host device. The hub acts as a central connection point, allowing multiple devices to be connected and used simultaneously. By using a USB hub, users can easily expand the number of USB ports available on their computer or device, making it convenient to connect and use multiple USB devices at the same time.

Explanation
A microphone is a type of peripheral device that is used to record sound. It is designed to capture audio signals and convert them into electrical signals that can be processed and stored digitally. Unlike speakers, which are used to output sound, a microphone is used to input sound into a computer or recording device. It is commonly used for various purposes such as voice recording, audio production, communication, and speech recognition.

Explanation
A barcode reader is commonly found in retail stores and uses laser technology to scan and read barcodes on products. It is an essential peripheral for retail stores as it allows for quick and accurate inventory management, price checking, and checkout processes. The laser technology used in barcode readers helps in capturing the barcode information efficiently, making it a reliable and widely used peripheral in the retail industry.

A biometric device is a device that uses unique physical or behavioral characteristics of an individual to authenticate their identity. A fingerprint scanner is a perfect example of a biometric device as it captures and analyzes a person's fingerprints to verify their identity. This technology is commonly used in various applications such as access control systems, mobile devices, and law enforcement. The other options mentioned, wireless mouse, wireless keyboard, and thumb drive, do not fall under the category of biometric devices as they do not rely on unique human characteristics for identification.

Explanation
